I have always wanted to do a mini itx. I also wanted to use all Noctua fans in a build. Currently the 8700k and 1080ti are the gaming flagships. So I decided to do my mini with both of those and a massive Noctua NH-D15 CPU cooler. It is a TIGHT fit. The cooler is actually bent in a little bit on both sides due to the fans. But everything is kosher and is running great at 5.0ghz OC. And no . . . there are NO cooling issues. Prime 95 pushes this system, but it stays below 80c.
